Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image management apparatuses fail to display captured images that specifically include the specified three-dimensional coordinates on a construction, leading to a lack of precision in image selection for inspection targets.
Innovation Solution
An image display apparatus that includes a storage unit for three-dimensional models and captured images, with operational units for accepting view operations and positional information, allowing retrieval and display of optimum captured images based on specified positions and priority levels, using a captured-image determining unit to assess images for facing, distance, and overlap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple captured images are retrieved based on three-dimensional coordinates, then the completeness of image coverage is improved, but the difficulty of selecting the optimal image increases
Solution Approach 1:
The patent applies parameter changes by evaluating multiple captured images based on specific parameters including image capture position, image capture direction, and overlap ratios. The system calculates these parameters for each retrieved image and uses them to determine the optimal image, thereby resolving the contradiction between comprehensive image coverage and selection complexity through systematic parameter-based evaluation
Solution Approach 2:
The patent implements preliminary action by pre-calculating and storing image capture positions, image capture directions, and overlap ratio information for each captured image in advance. When a retrieval request is made, the system directly uses these pre-computed parameters to quickly determine the optimal image without performing complex real-time calculations, thus reducing selection complexity while maintaining reliability
2Productivity
If images are selected based on segment identification, then the efficiency of inspection target retrieval is improved, but the precision of position-specific image display deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the construction into multiple segments and creating separate image groups for each segment. The system identifies the target segment and retrieves images specifically associated with that segment, thereby improving retrieval efficiency while maintaining position precision through segment-based image organization and retrieval
Solution Approach 2:
The patent implements local quality by evaluating images based on their specific capture positions and directions relative to the target position on the construction. The system calculates the overlap ratio between each image and the target position, and prioritizes images with higher overlap ratios, ensuring that the selected image precisely covers the specified position while maintaining efficient segment-based retrieval

AI summary
When a three-dimensional model of a photographic subject is displayed on a display, and a view operation for, enlarging the three-dimensional model is performed, a desired position on the photographic subject can be easily specified. After a desired position on the photographic subject is specified, a three-dimensional position, on the three-dimensional model, corresponding to the position is identified, and a plurality of captured images each including a pixel corresponding to the identified three-dimensional position are retrieved from a group of captured images obtained by image capturing of the photographic subject. An optimum captured image is determined from among the plurality of retrieved captured images or the priority levels of the plurality of retrieved captured images are determined. The determined optimum captured image is displayed on the display or some or all of the plurality of captured images are displayed on the display in accordance with the determined priority levels.
